As a child I was pretty unpopular. I was in a very small year group which didn’t help but I was always left out or on the periphery. I had one close friend outside of school from my swimming lesson but she was pretty quirky herself.
I made good friends at secondary, ups and downs and I did fall out with some on and off but I’m solid friends with about 6 or 7 now, still, some closer than others.
Same at university, don’t see each other much now we have DC but there was a little group of us.
I haven’t made loads as an adult but a few along the way - baby groups, school mums, work etc.
I’m definitely not “popular” though. There were the popular/cool kids at school and I wasn’t one of them. There’s a group of parents at my DC school who you just knew were the popular kids at school - still like it now and cliquey. Their kids are the same.
My DC are “unpopular”. Eldest is 7 and has two friends, struggles with the other kids. Littlest is still young but definitely not one of the “popular” ones. DH also similar as a child but made a decent group at secondary.
My parents are the same. I worry so much for my DC as I had a miserable time at primary.
